Long before he becomes the seven-seas trading king readers meet in the main Magi series, young Sinbad is singled out by the wandering magi Yunan and pointed toward Baal, the first Dungeon to appear in the world. Warriors from Reim are climbing it at the same time, and Sinbad clashes with a noble nicknamed Drakon on the way up before emerging as the first person ever to conquer a Dungeon. This 70-page one-shot was the trial run for the full-length Adventure of Sinbad spin-off that followed.
